WASHING-MACHINE.

Patented May 9, 1911 Application filed July 23, 1910. Serial No.573,530.

To all whom it may concern:

Be it known that I, ARTHUR M. BURN- HAM, a citizen of the United States,and a resident of Gardiner, in the county of Kennebec and State ofMaine. have invented certain new and useful Improvements in\Vashing-Machines, of which the following is a specification.

My invention relates to machines for Washing fabrics and has for itsobject the provision of a machine that very closely imitates the rubbingadministered by hand on the familiar wash-board, and consists in theprovision of a corrugated roller that is mounted to rotate in a suitablyconstructed receptacle, and a rotary brush journaled in the free end ofa pivoted frame and connected to a footpiece to hold the brush in thedesired position relative to the roller in order to wash the clothes.

My invention will be described in detail hereinafter, and illustrated inthe accompanying drawings, in which-- Figure 1 is a longitudinalsectional view of my improved washing machine; Fig. 2, a top plan View;and Fig. 3, a view on a reduced scale of the hand-board removed.

In the drawings similar reference characters will indicate correspondingparts throughout all of the views.

The receptacle 1 of my improved device is made preferably of sheet-metaland has its sides vertical, while the ends are inclined. The corners ofthe receptacle are reinforced by angle-pieces 2 that are extended belowthe bottom of the receptacle and have legs 3 secured thereto. At one endof the receptacle the corner-pieces 2 are extended above the topthereof, as shown at 4. and a shaft 5 is journaled therein, havingbelt-pulleys 6 and 7 secured thereto.

8 indicates a tubular shaft loosely mounted on shaft 5, and 9 armssecured to the shaft 8 and having a cylindrical brush 10 journaledtherein with a pulley 11 secured thereto to one of its trunnions andgeared to pulley 6 by means of belt 12.

13 indicates a corrugated scrubbing-roller journaled on the sides of thereceptacle 1 adjacent to the end farthest removed from the end on whichshaft 5 is journaled, said roller having a pulley 14 secured to one ofits trunnions that is geared to pulley 7 by means of crossed belt 15, sothat when in operation the roller and brush will pull the clothes intothe receptacle. Shaft 5 may be rotated by a crank-handle l6.

18 indicates a cross-bar connecting arms 9 and 19 a coil-spring mountedon shaft 8,

and having one end engaging cross-bar 18 and the other end the end ofreceptacle 1. Said spring normally lifts the brush from engagement withthe roller 13.

20 indicates a shelf mounted by means of bolts 21 on arms 9, on whichcakes of soap may be placed, said shelf being adapted to be adjusted bymeans of the bolts to cause the soap to bear heavily or lightly on thebrush, as desired, for the most cflicient operation of the machine.

22 indicates a rod secured to each arm 9, and 23 a foot-bar secured tosaid rods, said bar being conveniently placed for operation by theoperator of the machine to regulate the pressure of the brush on thefabric being treated.

24L indicates a hand-board having its side edges provided with flanges25, and a flange 26 that engages the inner side of the end of thereceptacle 1 adjacent to roller 13.

27 indicates arms secured to the side flanges and engaging pins 28 and29 on the sides of the receptacle to hold the board in place.

In operation the fabric to be treated is placed on board 241- and roller13 and the arms 9 swung dowmvardly by depressing foot-bar 23, so thatthe brush 10 engages the top of the fabric. Then by resisting thetendency of the brush and roller to pull the clothes into the receptaclethe fabric is effectually scrubbed, being allowed to be gradually pulledinto the receptacle as the cleansing progresses.

Having thus described my invention, what I claim is- 1. In awashing-machine, a receptacle. a scrubbing-roller journalcd in saidreceptacle, a shaft journalcd in the receptacle, arms pivotally mountedon said shaft. a brush journaled in said arms, gearing connecting theshaft aforesaid and the roller and brush, and means to move the brushtoward and from the roller, substantially as shown and described.

2. In a washing-machine. a receptacle, a scrubbing-roller journaled insaid receptacle, a shaft journaled in the receptacle, arms pivotallymounted on said shaft, a brush journaled in said arms, gearingconnecting the shaft aforesaid and the roller and brush, a soap-shelfadjustably secured to said arms adjacent to said brush, and means tomove the brush toward and from the roller, substantially as shown anddescribed. 4

3. In a washing-machine, a receptacle, a scrubbing-roller journaled insaid receptacle, a shaft journaled in the receptacle, arms pivotallymounted on said shaft, a brush journaled in said arms, gearingconnecting the shaft aforesaid and the roller and brush, a spring tonormally hold the arms in a raised position, and a foot-bar to depressthe roller against the resistance of the spring, substantially as shownand described.

4. A washing-machine comprising a receptacle, a corrugated rollerjournaled in said receptacle, a drive-shaft journaled in the receptacleand having pulleys secured thereto, a tubular shaft loosely mounted onsaid drive-shaft, arms secured to said tubular shaft, a brush journaledin said arms, a soap-shelf adjustably mounted on said arms, a springengaging said arms and normally tending to raise them, gearingconnecting the pulleys on the drive-shaft and the roller and brush, anda hand-board removaloly secured to the receptacle, substantially asshown and described.

In Witness whereof, I have hereunto set my hand in presence of twosubscribing Copies of this patent may be obtained for five cents each,by addressing the Commissioner of Patents, Washington, D. C.
